face of the large cam-plate 25. The engagement of this cam-lug and rollwill operate at the proper time, presently to be. mentioned, to breakthe clutch engagement of the driving-pulley and collar 37 and stop theInachine.

37a is a coiled spring` on the driving-shaft 23 to bringabout therengagement of collar 37 and pulley 24.

The lever 3S is jointed at e, so that its forward or free end 38 may beraised sufficient to clear the roll 10 from the cam-lug 41, and thusallowthe spring 37 to bring about such rengagement.

The operation is as follows: The knife is placed in position shown atFig. 4, with the cutting edge down, and while the forward end of theframe is elevated. When, therefore, the cam-plate 25 has been turned tobring the roll 27 on the lowest point of said camplate, the back of theknife-blade will be just below the center of the glazing-wheel, and whenthe machine is started the blade is reciprocated rapidly across the faceof the wheel, while at the same time the knife-supporting end of theframe is being gradually raised by the cam-plate 25, and when the saidcamplate is in the position shown at Fig. 4 the edge of the knife-bladewill have been raised above the center of the glazing-Wheel and theoperation of glazing on that side of the blade will have been completed.In the meantime the cam-plate will still continue to lift the forwardend of the frame and carry the blade above the glazing-Wheel until thehighest point of the cam-plate has been reached, when the engagement ofthe roll 40 of the cam-lug will stop the machine. The knife is thenreversed by placing the handle in the hook-supports 20, so as to glazethe opposite side of the blade. The forward end 38 of the lever 38 isthen raised to disengage its roll 40 from the cam-lug 41, and-thereby,as before mentioned, restart the machine. As the cam is at this time atits highest point, the first impulse of said cam in its rotativemovement will be to cause the roll 27 to drop from the highest to thelowest point of the cam. This drop will bring the knife-blade again intooperative position with respect to the glazing-wheel, and the side ofthe blade nearest to said wheel will be finished` by the two motionsabove mentioned-viz., the reciprocating and elevating. The pressure ofthe blade against the Wheel is regulated by thenutsl.Compressingthetension-springs 8 and 9 lightens the pressure, whileelongation of said springs increases the pressure.

It will be observed (see Fig. l) that the reciprocating bar 17 isthinned down at the point 17h immediatelyunder the knife-blade. This isdone to give a little spring of the bar at that point.

While I describe the machine as a glazing-machine, it will be understoodthat by simply changing the wheel it is applicable for grindingknife-blades.

From the foregoing description it will readily be seen that the machine,being automatic blade, beginning at the back, isl drawn backward andforward across the face of the wheel, and at the same time the blade isgradually rolled toward the edge, thus preserving this convex surface.In my improved machine this conveXity is preserved by the circularmovement of the frame oscillating on the bar 3.

It will readily be seen that the adjustingrods 11 and 12 could bedispensed with, and the spring-rods 8 and 9 could be threaded a portionof their length sufficient to effect the necessary adjustment of thehead 4 to and` from the bar 3.

Having thus described my invention, what I claim as new,and desire tosecure by Letters Patent, isy 1 In a machine of the character described,comprising, in combination with a polishingwheel, an oscillating frame,adapted to be automatically operated, a support therefor, anautomatically-reciprocatingknife-supporting slide mounted on said head,means for gradually elevating the knife-carrying end of said i framewhile the reciprocating knife-support is in action, for the purpose setforth.
